在整个的小学数学学习过程中,加减法的学习是基础,也是重中之重,学生之后所进行的一切数学学习都是在加减法的基础上所衍生出来的,因此,加减法的学习也是数学领域发展的根本。新课标要求学生掌握基本的运算方法,并扎实掌握加减法的运算技巧。学生加减法运算水平的高低直接决定了他们在小学数学学习中所收到的效果,因此,作为小学数学教师,我们要将加减法的教学作为一项重点问题来抓,实施有效的教学,帮助学生更好地掌握基础的运算规律,充分激发学生的数 In the whole process of primary school mathematics learning, addition and subtraction is the basis of learning, but also the most important, all students after the mathematics learning are based on the addition and subtraction derived from, and therefore addition and subtraction Learning is also fundamental to the development of mathematics. The new curriculum requires students to master the basic computing methods, and a solid grasp of the addition and subtraction arithmetic skills. Therefore, as a primary school mathematics teacher, we should take the teaching of addition and subtraction as a key issue to implement effective teaching , To help students better grasp the basic computing rules, and fully stimulate the number of students
